in my attached example, I have a contact problem:
- a cylinder is in contact with a block
- the cylinder is not constrained, the block is moved by a pressure load
- I want to define the traction between the cylinder and the blocked when they are sliding. Following the thread www.comsol.com/community/forums/4-1/thread/13214/, I used the formula ks*(u-src2dst(u)) for the contact boundary load.
My question is: why the cylinder (which is not constrained) does not move with the block, but it keeps the block from moving? Only when a small value of ks, the cylinder will move?
If I want the cylinder move with a large value of ks, what is the correct way to do?
Thank you very much for your helps.
